Taboola is trading 5.5% down at $2.06, extending its selloff after its November 4 earnings report as Q4 revenue guidance missed analyst consensus. - Q4 revenue outlook was $477–$493 million, below the $533.9 million consensus; Q3 revenue fell 6.9% year over year. - Profitability gains were outweighed by revenue-pressure concerns, including impression-volume headwinds and a slower-than-expected Next Engage rollout. - Software-sector weakness may add pressure, although broader U.S. indexes were higher.
